Hmm when the ak.imgfar thing came up on my computer it "paused" ie. froze but just for a few seconds. It's sounding suspect. After is saw the ak.img thing I shut down spyware doctor and it seemed to go away. I'm going to keep my eye out for it again, i'll try and see what causes it to appear. Sure sounds like it's the root of the troubles.
I'd definitely try running a spyware program, it really sounds like this could be a spyware problem. AVG anti-spyware is a separate program from AVG anti-virus, you have to download them separately. Is it AVG anti-virus you have or AVG anti-spyware? Maybe you already have both?
I'll keep watching for it, see if I can't find some help for you.
Anyone else seeing this ak.imgfar thing??
